' mPRovEn MACHINE: PoR rrmsn'me LEATHER, PAPER,- ac.

Tho Schedule referred to these Letters Patent n u making part of the seme To all whom it may concern Be it known that I, PETER Fuhrmann, of the city and county of Albany, State of NewYork, have in? the modes of eilecting the breaking of the said con'-.

tact. t

Figure 3 represents a section of another device for the same purpose. l

In operating with the finishing-machines nownsed lfor finishing morocco, splits, 85e., the operator or person has but little'or no control over the machine, and

consequently cannot care as he should for the piece of morocco o'r'other leather being operatedv upon, as

Ithe roller, glass, or other tool used in the machine cannot be readily removed from'contact with the spring-bed on which the pelt is worked. In consequence of this inability on the part of the operator,

the weak or jagged parts often` catch and cause the pelt to .teau I By my invention, I give the operator an easy and sure mode-of breaking the contact of the dummy,

roller, glass, or dint Awith -thepelt `while being operated upon, and. of throwing it` again in contact.

This I may do Tin several ways: rst, by causing the spring-bed, on which the pelt is placed, to fall at one end bymeans of a handled tumbler, hinged tothe frame of the table, which can berthrown down in an instant; or by a duplication of the same, connected Vby a rod; or by knuckle-jointlevers; or by a tumbler 'or knuckle-joint levers, operating. against the lower side of the spring-plank above; orby cams or eccentrics, arranged to operate in the same manner as the tumblers or levers, placed so as to effect the same with either the spring-bed or the spring-plank.

To enable others skilled in the-art to make and use the device, or its several 'modifications by which I efect the breaking of the said contact of the roller, dummy, or other tool used withv the spring-table bed, I'will proceed to describe my invention, in @reference to the accompanying drawings, and their letters of reference, the same letters indicating similar parts.

A, fig. 1, represents' any suitable frame, or it may f be the sides and ceiling of a room, in which is fixed a part of the apparatus used in this invention.

B, iigs. 1 and 2, represents a table, placed under the pitman O, which holds and works ther'oller s, or

dnm'my, glass, or other tool to be used to operate upon the pelt, leather, or paper which is to be worked, lwhich is laid on the table B. V

YThe pitman. O, ligs. l, 2, and 3, is hung from above fro'm a spring-plank, D, properly secured, at its rear end, to the tiuibers of the fratrie A or building.

, To give stiffness to the spring-plank I), a screw-cut 'crank-shaft, a, iigs. 1, 2, and 3, is used, by which a greater or less amount of pressure is secured from the said spring-plank.

The pitman C is operated by a second pitman, E, fig. I, which is Worked by a crank, F, or fly-wheel, moved by any suitable motor. y

The pitman (l, suspended over the table B, works directly over a spring-table bed, fn., igs. 1 an'd 2, which table-bed n is placed in the centre of the table B.

In operating, the pitman G, with its tool s, works over vand on the spring-table bed u, from one end of the same to the other, as shown by dotted lines in ii 2.

gWhile thus operating, the leather or paper is placed on the spring-table bed n, when it is polished by the vfriction of the roller s, or its equivalent, passing over its face.

,If, in the process of polishing, the leather being operated upon be weak or ragged, the roller s is apt to catch and tear, and to prevent this, I break the contact of the roller s, or its equivalent, with the spring-table bed. n,'on which -the leather is worked. This I may do in several ways.

One way is by the means of a tumbler, o, gs. 1 and 2.

This 'tumbler is made .in form asV shown, and is hinged to a lower timber, m, of the table, iig. 2, and is provided with a handle, fr, by which it may be thrown down, as in iig. 1, or as in iig. 2.

When thrown up, as in iig. 2, the spring-bed n is in position to work, and when thrown down, as in fig. 1, the roller s swings clear of the spring-bed from end to end, and the said lroller will not be brought in contact with any leather laid thereon,

An eccentric or lever, properly placed, will secure the same result, or two tumblers, or their equivalents, namedplaced at each end under the said 'spring-bed, and connected by a common jointed rod, that will lower the whole spring-bed, will also elect the same.

When the said contact is broken from below, as in iig. 2, I place a stop, p, under the spring-.plank D, figs. 1 and 2.

This stop screws through a timber, q, and may be lowered or raised, as may be desired, and is intended to catch the plank I), and prevent it from falling down and carrying the pitman and its tool s with it whenthe spring-table bed n is'lowered.

Or, again, a tumbler, o', fig. 3, placed to work under the spring-plank Dya's in iig. 3, may be. used and operated by a shaft, furnished with a suitable pulley, or

its equivalent, not shown, or eccentries, or jointed Breaking instantaneously the contact of the roller levers may be used, and in either of these cases the s, or its equivalent tool, with the hinged spling-bed n, stop pis dispensed with, and the spring-bed of the by means of the hinged tumblero, acting in connectable is made rm. tion with the stop p, or its equivalent, substantially as These several devices are some of the means by described, for the purpose set forth. which the breakage of the contact of the roller s with PETER FABRELL the spring-bed is e'eclcd, as well as the throwing of the same in contact, at pleasure.
